LayoutManager not setting stackFromEnd and reverseLayout Kotlin

Question

inside an activity I have an observer I am calling a function to setup adapter. After that I am setting list to my adapter. And doing How to know when the RecyclerView has finished laying down the items?. And setting layout manager on that. But it's not working.

activity.kt

class activity : BaseActivity() {

 private var cAdapter: cdAdapter? = null

    fun setupObserver(){
       viewModel.list.observe(this, { value ->
            if (cAdapter == null) {
                setupAdapter()
            }
            submitList(value)
            binding.cRecyclerView.afterMeasured {
                layoutManager = LinearLayoutManager(this.context).apply {
                    direction(this)
                }
            }
        })
    }
    
   private fun setupAdapter() {
        cAdapter = cdAdapter()
        binding.cRecyclerView.adapter = cAdapter
   }
  
   private fun direction(linearLayoutManager: LinearLayoutManager) {
        linearLayoutManager.apply {
           // if (binding.cRecyclerView.canScrollVertically(1)) {
            //    logE("Yes can scroll")
            //} else {
            //    logE("No scroll")
            // }
              
            if (viewModel.itemsAreMorethanTwo()) {
                stackFromEnd = true
                reverseLayout = true
                val index = viewModel.findLastBiggerValue()
                if (index != null && index >= 0) {
                    scrollToPosition(index)
                }
            } else {
                stackFromEnd = false
                reverseLayout = true
            }
        }
    }

     inline fun <T : View> T.afterMeasured(crossinline f: T.() -> Unit) {
        viewTreeObserver.addOnGlobalLayoutListener(object : ViewTreeObserver.OnGlobalLayoutListener {
            override fun onGlobalLayout() {
                if (measuredWidth > 0 && measuredHeight > 0) {
                    viewTreeObserver.removeOnGlobalLayoutListener(this)
                    f()
                }
            }
        })
    }
}

Basically inside direction function I am checking that if item has more than two value, i'm using reverse layout as well as stackFromEnd as true. As you see inside direction function some lines are commented and I need to check that my items are less than the whole height, i.e. I don't want to scroll up or down and the whole items consist in a single screen

1. For the commented section, I want to know if the view is scrollable or not.

2. the code below is working and above code is not.

If I move this code from observer

binding.cRecyclerView.afterMeasured {
    layoutManager = LinearLayoutManager(this.context).apply {
         direction(this)
    }
}

inside like this

private fun setupAdapter() {
         cAdapter = cdAdapter()
            binding.cRecyclerView.apply {
            adapter = cAdapter
            layoutManager = LinearLayoutManager(this.context).apply {
                setLayoutDirection(this)
            }
       }
    }

When I move this piece of code in setupAdapter the commented section does not work though it sets the layout manager correctly. What I am doing wrong in above code? Please suggest me something.
